That's why some people here are asking for a scientific approach to the IS/IT issue.
And it's not happenning. Why?
Yeah, it is.
Take the Modern Aikido world and think of all of them in a room.
Then take the IP/aiki people and put them in a room.
The Modern Aikido room is the control. The base. It's all the same in regards to comparisons to the IP/aiki room.
Now, slowly take subjects from the control room and add them to the IP/aiki room. Allow saturation. Remove subjects and report results.
The results? 100% of subjects state that what the IP/aiki people are doing is *not* what Modern Aikido people are doing. It is *different*.
I don't think you can get any closer to a scientific approach than that in this field/study/area of IP/aiki.
